Using the Linux ISO

The Linux ISO contains all the workshop data and material, it runs an instance of Ubuntu 12.04 (32-bit) customized for the workshop by GeoSolutions containing the following software:

  1. The OpenJDK Java 1.8 and Tomcat 7.0.75 Servlet Container

  2. GDAL libraries and FWTools 2.0.6

    Note

    FWTools is a set of GIS utilities for handling and manipulation of GIS data. FWTools includes OpenEV, GDAL, MapServer, PROJ.4 and OGDI as well as some supporting components.

  3. An instance of GeoServer 2.10.x configured with some datasets and extensions, like RESTConfig, ImageMosaic, ImagePyramid, Chart Dynamic Symbolizer

  4. The most popular GIS clients like GoogleEarth 5.1, uDig 1.3.1 and QGis 2.8.1

System Requirements

Minimum Requirements:

  • 1 Core
  • 3Gb RAM

Suggested Requirements:

  • 2 Cores
  • 4Gb RAM

If you want to install the training system on a phisical or virtual machine, the minimum disk space required is:

  • 20Gb hard disk space

Launch the Linux ISO

The Linux ISO contains a fully functional version of Ubuntu 12.04 (32-bit). It can start automatically running directly from the DVD or USB.

In order to launch the Linux ISO the steps to do are the following:

  1. Make sure the boot sequence on your PC allows to check CD/DVD or USB before HD

    • First you must start your computer. During the boot process, usually on the first or second screen your monitor displays, you will be able to see a message such as “press f8 for set up” or “press ctrl-alt-del to enter setup”. Different machines require you to enter CMOS setup in different ways but your individual computer should given you a hint of how that is done in the boot screens.
    • Once inside BIOS/CMOS setup you are going to to explore the environment. Usually the arrow keys will allow you to move between utilities but your computer may require you to use additional keys or a different set of keys altogether. Therefore it is important you familiarize yourself with your version of CMOS before making any changes.
    • Now that you’re a little more comfortable with CMOS go ahead and browse through the entries until you see the boot sequence. Select this utility and change it according to what sequence you wish to put in place (make sure to move the DVD/USB key on top of the list to make the machine boot from them instead of booting from the local hard drive).
    • Finally double check what you have done to ensure you made the correct choices. Save your new sequence and press the Esc key when you are done. This should bring you back to boot up and depending on the changes you made it may be required to restart the computer to enable the changes you just made.
  2. Make sure the DVD is correctly inserted in the DVD-ROM Reader (or the USB is connected) before PC boot sequence.

  3. When the computer starts you should see a choice screen like the following:

    ../_images/dvd_run1.jpg

    First boot

  4. Press ENTER or type ‘live’ and press ENTER to startup the system from the DVD/USB.

    Note

    Ignore the other options for now, we will inspect them later in the guide.

  5. If the Linux ISO runs correctly with no errors, you should see at the end the Ubuntu login as depicted below

    Ubuntu GUI

  6. Use the following credentials to log in

    • username: geosolutions
    • password: Geos

Installing the Linux ISO

Note

This step is alternative to the ‘live’ launch of the Linux ISO

The Linux ISO can also be installed on a system instead of running it ‘live’. This has the advantage of shorter loading times more performance and nicer user experience as well as persistence of the changes made during the training.

The Linux ISO can be installed on a physical host or a virtual one. To install the Linux ISO on the system follow the steps above and choose install instead of live in the choice screen.

Follow the on-screen steps to complete the installation.

Verify Everything Works Correctly

  1. Use the following credentials to log in

    • username: geosolutions
    • password: Geos
  2. Open Firefox and click on the first GeoServer bookmark

  • The GeoServer administration page should load

Note

On low spec hosts GeoServer can take up to 5 minutes to start up

  1. Click on “Layer Preview”, search for Boulder and open the layergroup “Boulder”
  • The preview should load
  1. Open pgAdmin III and doubleclick on the “postgres” server
  • A list of databases should open
